This European Standard specifies the general requirements for central power supply systems for an 56 independent energy supply to essential safety equipment. This standard covers systems that are permanently connected to AC supply voltages not exceeding 1000 V and use batteries as an alternative power source. Central safety power supply systems are intended to ensure energy supply to emergency escape lighting in the event of normal supply failure and may be suitable for energising other essential safety equipment, for example: - electric circuits of automatic fire extinguishing installations; - paging systems and signalling safety installations; - smoke extraction equipment; - carbon monoxide warning systems; - special safety installations related to specific buildings, e.g. high-risk areas. Combination of the aforementioned equipment types should not be mixed together on the same central safety power supply system. Schematic representations of typical central safety power supply equipment are depicted in Clause 4. Power supply systems for fire alarm equipment that are covered by EN 54 are excluded.
